, Be it f known that CA L E. IERICQQNI and JOHN MAnvINf Emoso ,f citizens'-of the f United Statesi'-o:E America, residing at El Campo, in the county. of'lVharton' and State otllexasy have invented new and useful'lnr provements in Type Cleaners for Typewrit (r Machines of which the followingi's a specification.

The object of the sta ion is to i r $v 11'; a simple and efficient means for maintain ing the typefaces of a typewriting'machine 8 in proper condition free from accumulations of lint, dust ,andother foreign substances in the operation thereof without resorting to the operation of specifically cleaning the same as in the ordinary practice; and with this object in view the invention consists in a construction and combination of parts of which a preferred embodiment is shown in *the accompanying drawings, wherein Figure l is a'plan view, and

of the brush head and adjacent portions of the device. I

' The device consists essentially of a brush head 10 of looped form with the opening of the loop directed downwardly and, having side arms ll consisting of twisted strands of wire or the equivalent thereof from which project bristles 12 arranged to invade the throat or open space between the sides of the loop and bridge or span the latter jointly 7 so that type 13 carried by thetypebars 14 must pass through the bristles or the space normally occupied by the bristles in an manual cleaning of the type facesisf avoided.

In the illustrated embodiment ofthe illvention the looped brush head is carried by a bracket having'arms 16 connected bya central" arch 17 and provided with terminal "fingers 18 which are'inwardly directed and have at their extremitiestheoutwardly fac Figure 4c is an enlarged detail side view.
